The relative pronouns are:

Subject Object Possessive
who who/whom whose
which which whose
that that -

We use relative pronouns to introduce relative clauses. Relative clauses tell us more about people and things:

Lord Thompson, who is 76, has just retired.
This is the house which Jack built.
Marie Curie is the woman that discovered radium.

We use:

  • who and whom for people
  • which for things
  • that for people or things.

Two kinds of relative clause

There are two kinds of relative clause:

1.  We use relative clauses to make clear which person or thing we are talking about:

Marie Curie is the woman who discovered radium.
This is the house which Jack built.

In this kind of relative clause, we can use that instead of who or which:

Marie Curie is the woman that discovered radium.
This is the house that Jack built.

We can leave out the pronoun if it is the object of the relative clause:

This is the house that Jack built. (that is the object of built)

Relative pronouns 2

Be careful!

The relative pronoun is the subject/object of the relative clause, so we do not repeat the subject/object:

Marie Curie is the woman who she discovered radium.
(who is the subject of discovered, so we don't need she)

This is the house that Jack built it.
(that is the object of built, so we don't need it)

2.  We also use relative clauses to give more information about a person, thing or situation:

Lord Thompson, who is 76, has just retired.
We had fish and chips, which I always enjoy.
I met Rebecca in town yesterday, which was a nice surprise.

With this kind of relative clause, we use commas (,) to separate it from the rest of the sentence.

Be careful!

In this kind of relative clause, we cannot use that:

Lord Thompson, who is 76, has just retired.
(NOT Lord Thompson, that is 76, has just retired.)

and we cannot leave out the pronoun:

We had fish and chips, which I always enjoy.
(NOT We had fish and chips, I always enjoy.)

whose and whom

We use whose as the possessive form of who:

This is George, whose brother went to school with me.

We sometimes use whom as the object of a verb or preposition:

This is George, whom you met at our house last year.
(whom is the object of met)

This is George’s brother, with whom I went to school.
(whom is the object of with)

but nowadays we normally use who:

This is George, who you met at our house last year.
This is George’s brother, who I went to school with.

Relative pronouns with prepositions

When who(m) or which have a preposition, the preposition can come at the beginning of the clause:

I had an uncle in Germany, from who(m) I inherited a bit of money.
We bought a chainsaw, with which we cut up all the wood.

or at the end of the clause:

I had an uncle in Germany, who(m) I inherited a bit of money from.
We bought a chainsaw, which we cut all the wood up with.

But when that has a preposition, the preposition always comes at the end:

I didn't know the uncle that I inherited the money from.
We can't find the chainsaw that we cut all the wood up with.

when and where

We can use when with times and where with places to make it clear which time or place we are talking about:

England won the World Cup in 1966. It was the year when we got married.
I remember my twentieth birthday. It was the day when the tsunami happened.

Do you remember the place where we caught the train?
Stratford-upon-Avon is the town where Shakespeare was born.

We can leave out when:

England won the World Cup in 1966. It was the year we got married.
I remember my twentieth birthday. It was the day the tsunami happened.

We often use quantifiers and numbers with relative pronouns: 

all of which/whom most of which/whom many of which/whom
lots of which/whom a few of which/whom none of which/whom
one of which/whom two of which/whom etc.

She has three brothers, two of whom are in the army.
I read three books last week, one of which I really enjoyed.
There were some good programmes on the radio, none of which I listened to.

Hello kakakevin,

We can use both 'that' and 'which' in defining relative clauses, but we cannot use 'that' in non-defining relative clauses.

Your example sentence contains a defining relative clause and so both 'that' and 'which' are possible; neither is incorrect.

Hello Peter.
I was woken up by some strange noise ......... the apartment above mine.
1. which was coming from
2. which came from

Hello amirfd,

Both are possible here. Which you choose is a question of preference and context.

Generally, we don't provide answers to questions from elsewhere like this one. If we did, then we would end up doing people's homework and tests for them!

in the fourth question i can't understand why the answer in "which but not that " could you explain this for me please ?

Hi omarmohamed99,

'which' is correct because it refers to the entire phrase before the comma. 'that' isn't used to refer to a situation or action in this way.

All the best,

Dear teachers,

I have a question for you. I wrote this sentence in an essay:

Tyrion Lannister is one of the characters of a Song of Ice and Fire who belong to the category of "cripples and bastards and broken things".

I was corrected by someone who speaks a better English than me, but now I'm confused. She said that I should have written "belongs" instead of "belong", and that "who" is always used with the third person.
I had used a plural word because the verb refers to a group of people.
Could you help me to better understand?

Thanks in advance!

Hello Lady Olenna,

Both forms are possible, with a small shift in meaning.

 

Tyrion Lannister is one of the characters of a Song of Ice and Fire who belongs to the category of "cripples and bastards and broken things".

 

 

The singular verb here tells us that it is Tyrion who belongs to this group: he is one of the characters of the book and he belongs to this category.

 

Tyrion Lannister is one of the characters of a Song of Ice and Fire who belong to the category of "cripples and bastards and broken things".

 

The plural verb here tells us that there are many characters who are in this category and Tyrion is one of them: there are a number of characters who belong to this category and Tyrion is one of them.

Thank you very much, Peter!

Dear Sir
Please help me to clarify this.
When using relative pronouns for animals which is the correct? For e.g.The puppy
which I bought is very cute. or The puppy that I bought is very cute. or The puppy
who/whom I bought is very cute.
Are all these correct or only the first and the second?
Please let me know.
Regards

Hello Andrew international,

For animals we use which or that, not who.
